What is that you want the widget to do? I adjusted the standard widgets to show album covers with name of artist and name of album on my own site have a look and see if this is what you would like the widget to do and I'll help you out with it.
No! I adapted the standard Xenforo widget to show the music albums. I had to manually edit the template for the topics, which basically meant I had to add certain things and move a few things around and add to extra CSS to make it work as you see it on my site. I would send this to you via email, but for some reason or other my email addresses are not liked by Google mail. BTW. I manually approved your account on my site because the email it sent out to you for confirmation bounced lol.
